Credit card sales staff in dire need of training and manners

I spent over 45 mins speaking to your *********** sales staff in the credit card division. I tried to upgrade my credit card from a titanium to a platinum card. I spent about 20 mins speaking to the first agent sharing all my details only to be told that I need to be transferred to retentions without any further explanation. I then spent another 20 mins speaking to another *********** person who refused to provide me with her name when I said that I would be writing a Hello Peter complaint. I asked her for her name at least 15 times and she refused point blank to give it to me. I called around 11:10 on 22 July. Pls get the supervisors to listen to the recordings as your staff are in dire need of training. As for me, I would gladly take my business and investments to a more competent bank. Your customer service is pathetic
